LOCKING MECHANISM non MoT.on-vErIIcI.Es.'

' To all whom it may concern:

Be it known that I, Mann LAvERNn TAY- LOR, a citizen of the United States, residing,

at POIlllltlQdll the county of Oakland and State of Michigan, have invented new and useful Improvements in Looking Mechanism for Motor-Vehicles, of which the following is a specification. y This invention relatesto improvements in locking mechanism for motor vehicles.

In carryingout thepresent invention, it

is my purpose to provide locking, mechanism for motor vehicles whereby the emergency brake lever may be locked in On position,- the gear shifting lever locked in neutral position, and the ignition circuit of the engine broken, thereby preventing theft of the machine.

It is also my purpose to provide mechacontrolled by the'emergency brake lever and inafter set forth in and falling within the scope of the claims.

which will be operatedto locking position when the emergency brake lever is swung to a position to apply the brakes.

With the above and other objects in View, the invention consists in the construction,

combination and arrangement of parts here- In the accompanying drawings;

3, as usual. Pivoted upon one side of the transmission gear case 1 is the emergency pending band brakes on the rear Wheels of the vehicle so that when the lever 4 is swung in one direction motion will. be transmitted I to the bands of the brakes to expand such bands against the drums, while when the lever is swung inthe opposite direction the brake bands will be contractedto release the drums.

Slidably position of the gear shifting lever is a hcrizontal rod 9 having the inner endadapted to enter an opening lO formed in the lever "whereby such lever may be locked in neutral mounted within an opening formed in -one side of thecasting formed .with the H-slot 3 adjacent to the neutral position. In the presentinstance, the rod 9 comprises axially aliningsections'll and 12 and surrounding the, adjacent ends ofithe sections 11 and 12 is a sleeve 13 fixed to the section 11 and'slidably 'receiving thesection 12. Interposed between the confronting ends of the sections 11 and 12 is an expansion spring 14,'while projecting outwardlyfrom the section 12 is a pin'15 working within a slot 16 formed in the sleeve 13, the

pin permitting the section 12 to slide Within the sleeve and preventing. accidental dis placement of the; section from the sleeve under the action of the springrl t. By means of this construction of therod, the latter. may move inwardly when the lever is-out of normal position and in thismovementof the rod, the spring 14 will be compressed'so that when the lever'is moved to neutral position, the section 12 wilhbeprojectedinto 1 the opening 10 in the gear shifting lever incident to the reactionofithe. spring 14.

hicle' asat 18 and having another angle formed with a slot 19 that receives a pin a triangular-. plate pivoted at carried by the outer end of; the section 11 of the. rod 9. The remaining angle" of the" plate 17 is connected throughigthe-medium of a link 2O1-with an 21 depending from Pivotally connected with a bracket 22 secured to the lower side of the footboard of the vehicle is a bell crank lever 23 and one limb of the bell crank lever 23 is connected pin and slot connection 27 with the remaining limb of the bell crank lever 23. The

upper end portion of the bar 26 is slidably mounted within a guide 28 secured to the inner face of one of the walls of the casing 25. Secured to said wall of the casing 25 below the guide 28 is a lock 29 and disosed in alinement with the bolt end of the Ooh 29 and spaced apart from such end of the lock is a keeper 30 adapted to receive a 'bolt. The lock and keeper are disposed at opposite sides of the rod 26 and the rod is formed with a slot 31 adjacent to the upper end thereof that is adapted to register with the keeper 30 when the rod 26 is elevated so that the bolt of the lock 29 may be projected through the slot 31 and into the keeper 30 to hold the rod 26 in elevated position. Se cured to one edge of the rod 26 is a block 32 of insulating material and fastened to the outer face of the block 32 is a contact strip 33, while disposed adjacent to the edge of the block 32 carrying the strip 33 is a block 3* of insulating material. The block 34 is equipped with pins 35, 35 spaced apartand adapted to be bridged by the strip 33 when the rod 26 is in lowered position.

\Vhen .the brake lever 4.- is in normal or Off position, the rod 9 is withdrawn from the opening 10 'in the gear shifting lever 2, and the bar 26 lowered so that the pins 35 are bridged by. the contact strip 33. The pins 35 and the contact strip 33 constitutea circuit breaker and this circuit breaker is connected in seriesin the ignition circuit of the hydrocarbon engine of the motor vehicle so that when the bar 26 is elevated the ignition circuit of the motor is broken. When the gear shifting lever 2 is in neutral position and the emergency brake lever 4: swun to On position the brake rod 7 is rotate with the effect to move the links 8 and so expand the brake bands to frictionally engage the brake drums to check the rotation of the wheels. In the movement of the brake rod 7 under the action of the brake lever, the link 20 is actuated to swing the plate 17 and in the movement of the plate 17 the section 12 of the rod 9 is thrown into the opening 10 in the gear shifting lever, thereby locking such lever against movement to shift the gears. Simultaneously with the movement of the link 20 motion is imparted to the bell crank lever 23, through the medium of the link 2i, thereby swinging the bell crank lever and elevating the bar 26 so that the opening 31 will register with the keeper 30. The bolt of the lock 29 may now be projected through the opening 31 in the bar 26 and into the keeper 30, thereby locking the bar 26 in elevated position. In the upward movement of the bar 26, the strip 33 breaks the connection between the 'contact pins 35, thereby breaking the ignition circuit of the engine. I

It will be noted that when the bar 26 is locked in elevated position, the ignition circuit will be held open, the gear shifting lever locked in neutral position and the brake lever held against movement.

In thepresent instance, the tumbler of the 36 that projects through an opening in the instrument board of the vehicle, as clearly' illustr ted in Fig. l of the drawings, and this s raft 36 is adapted to be rotated by means: of a key. Surrounding the shaft 36. is a braking sleeve 37 spanning1 the space hetweenthe dash board and t e instrument board as shown in Fig. 1.

While I have herein shown and described one preferred form of my invention by way i of illustration, I wish it to be understood that I do not limit or confine myself to the precise details ofbonstruction herein described.and delineated, as; modification and variation may be made within thoaoope of theclaims without'departing from-,the-spirit of the invention.
